In a few countries (e.g. Sweden) there is neither vaccination nor any antibacterial treatment of the meat. And salmonella is nearly a non-issue. Climate may be a factor, but probably not the only factor.
imho if we allow "cheap" treatments such as vaccination or preventive antibiotics, that also means we allow a cheaper way of keeping your animals healthy (cheaper than rigorous routines for hygiene/disease control/animal separation). if it's allowed to do so, it's a competitive edge, so it becomes standard practice.
